DETERMINATION OF TOTAL PETROLEUM HYDROCARBONS (TPH) IN WATER BY FLUORIMETRIC METHOD - Water and Wastewater

Total petroleum hydrocarbons (TPH) is a term used to describe a large family of several hundred chemical compounds that originally come from crude oil; the main and most specific part of these compounds are non-polar and slightly polar hydrocarbons of the aliphatic, aromatic and alicyclic structure. These compounds are harmful to humans and animals if absorbed through the skin, ingested, and inhaled thus claiming the analytical control of THP content in water as a global issue. Quantification of TPH in water is typically done using rather expensive chromatography techniques. Lumex Instruments developed fluorimetric method for cost-effective petroleum hydrocarbons in water determination using FLUORAT-02 analyzer. The method is based on measuring the fluorescence intensity of oil products after their extraction from water phase by hexane.
